How to Make Easy Salmon Onigiri

  1. Combine: In a cozy mixing bowl, blend the leftover salmon, kewpie mayo, and sriracha. Mix gently until everything is well integrated and the creamy sauce clings to the salmon.

  2. Mix: Add the cooked rice, rice vinegar, and mirin to your salmon mixture. Stir until the rice grains are evenly coated with the flavorful blend, creating a deliciously sticky texture.

  3. Shape: With clean hands, take a portion of the rice mixture and form it into triangular or oval-shaped onigiri. It should feel firm enough to hold together but soft to the touch.

Expert Tips for Easy Salmon Onigiri

Prioritize Freshness: Always use fresh leftover salmon. If it smells off or has an unusual texture, it’s best to avoid it for this Easy Salmon Onigiri Recipe.

Cool Rice: Ensure your rice is at room temperature. Hot rice will clump and make shaping difficult, leading to uneven onigiri.

Seal the Edges: When shaping the onigiri, press firmly to seal the edges. This will prevent them from falling apart during frying.

Perfect Frying: Use medium heat when frying to achieve a golden-brown crust without burning. Monitor closely as frying times may vary by stove.

Customize Flavors: Feel free to adjust the sriracha level or try different sauces in the salmon mixture for a unique spin!
